Abstract
    Surveys of an intertidal mudflat in Southampton Water in 2 successive winters (1972 and 1973) yielded a total of 12 bivalve spp, of which 5 contributed>99% of the biomass. The bivalve community is dominated by Cerastoderma edule (L.) (biomass, B=17-66g ash-free dry wt m-2; production, P=20-71gm-2 yr-1) and Mercenaria mercenaria (L.) (B=8-50gm-2; P = 4-14 gm-2 yr-1), although Mytilus edulis L. (B=4-5gm-2), Venerupis decussat (L.) (B=0.4-2gm-2) and V. aurea (Gemlin) B=0.6-1gm-2) are locally common. Total macrofaunal biomass (190gm-2) and production (220gm-2)yr-1) at Hamble appear to be higher than other comparable sites, although similar to mussel beds. The estimated transfer of bivalve biomass to predators (10.7 tonnes yr-1) and scavengers/decomposers (18.2 tonnes yr-1) shows the importance of the bivalve community to other trophic levels.
